Getting the DWARF types section is only implemented for ELF object files. We already disabled emitting debug types in clang (r337717), but now we also report an fatal error (rather than crashing) when trying to obtain this section in MC. Additionally we ignore the generate debug types flag for unsupported target triples. See PR38190 for more information. Differential revision: https://reviews.llvm.org/D50057 llvm-svn: 338527
